Cardas cables are designed with various conductor/dielectric geometries. Here is an explanation of some of the terms we use to describe our cables.
Symmetrical Quad-Axial -Four conductors, each the same AWG, arranged in a symmetrical pattern.
Perfect Mirror Quadaxial - Two concentric conductors, with the inside of one conductor tied to the outside of the other to create each lead. Used in Clear Speaker & Clear Light Speaker.
